In May 2025, surgeons at the University of Maryland Medical Center achieved a medical first that could reshape how complex spinal tumors are treated. They successfully removed a tumor from the top of a patient’s spine by entering through her eye socket—a route never before attempted in live surgery.

Why It Matters

Spinal tumors in the upper cervical and cranial junction region are notoriously difficult to access. Traditional approaches often require highly invasive procedures that involve opening the skull or working through the mouth, both of which carry significant risks of infection, neurological damage, or impaired mobility.

By taking an entirely new path through the orbit (eye socket), surgeons were able to reach the tumor with far less disruption to surrounding tissue. This was not a decision made lightly—prior to this operation, the technique had only been tested in cadaver studies, and its application in a live patient represented a bold leap forward.

The Procedure

The surgery itself lasted 19 hours and involved a multidisciplinary team of neurosurgeons, ENT surgeons, and craniofacial specialists. The surgeons carefully navigated around delicate structures of the eye to create a corridor to the spine. Using high-precision instruments and neuronavigation, they successfully excised the tumor while preserving critical nerves and vessels.

Patient Outcome

The patient recovered without recurrence of the tumor and was able to return to her daily life—demonstrating not only the feasibility but also the potential safety of this approach.

Future Implications

This landmark case shows that novel anatomical corridors can open new horizons in spine and skull base surgery. By pushing boundaries with minimally invasive concepts, surgeons may be able to reduce trauma, shorten recovery, and improve outcomes for patients with tumors once considered nearly inoperable.

The eye-socket approach is still experimental and not ready for broad application. However, as technology, imaging, and surgical precision continue to advance, this breakthrough underscores a powerful truth: innovation in spine surgery often comes from reimagining the routes we take to reach the most challenging problems.
